Gonk-o-rama!
If you want to time-shift AM/FM radio, try the "radioSHARK" by Griffen, the folks that make all sorts of nifty things for iPods. It is an external tuner with software that allows you to not only listen to radio, do "repeat" like the "back" button on your TiVo, but also to schedule recordings of radio broadcasts that you can listen to later, or even download to your iPod. I heard people saying it's $69 or such.
Now if someone could only make good ear-buds for us canines so that we could listen to OUR music on an iPod while out for a walk.
...but what do I know, I'm only a dog.
ARF ARF, says Iggy!
